A Fast Charger
Turn a low-cost SMPS into a battery charger
Published in issue 400, April 2010
Here’s how three Elektor readers came up with an idea for a fully automatic fast charger to keep the batteries in prime condition. This low-cost design uses an off-the-shelf switch-mode power supply coupled to an intelligent controller and can be easily adapted to charge other types of cell. • For fast chargeable 12 V lead acid batteries.
• 3.5 hour fast charge.
• Protected against short-circuit and reverse polarity connection.
• Optimised charging curve.
• Based on a modified low-cost industry standard SMPS.
• High efficiency from 76 %.
• Dead battery detection.
• The firmware supports 9 Ah cells, other cell capacities can be accommodated.
• Suitable for lead-acid and LiPo rechargeable cells.
